I encountered a problem with Kotlin Flow.
I copied the following code code from the Official guide
fun simple(): Flow<Int> = flow { for (i in 1..3) { delay(100) emit(i) } }
But the Android Studio prompts a following error:
No type arguments expected for class Flow
What am I doing wrong?

Make sure you use import kotlinx.coroutines.flow.Flow
not java.util.concurrent.Flow
, it gives you this error because Java concurrent Flow class take 0 type arguments, but Coroutines Flow take one
